CONDUIT' FOR ELECTRIC WIRES.

SPECIFICATION forming part of Letters Patent No. 391,587, dated October 23, 1888.

Application filed June 11, 1888. Serial No. 276,681. (No model.)

T0 at whom it may concern:

Be it known that I, IVIADISON DALLAS, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in a Conduit for Telegraph, Telephone, and Electric WVires; and I do declare the following to be a full, clear, and we act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in a conduit for telegraph, telephone, and electric wires in which a curbstone is made to operate, in conjunction with hangers and wires and ornamental metal plates, as a covering for wires; and the objects of my improvements are to provide a device whereby telegraph,te1ephone, and electric wires can be strung through the streets of a city and avoid the placing of wires underground or in an aerial position. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a perspective view showing metal plate covering wires in position. Fig. 2 is an end view showing curb-cap and hanger. Fig. 3 is a side view of curb-cap. Fig. 4. is a side view of hanger. Fig. 5 is an end view of plate.

Similarletters refer to similar parts through out the several views.

In constructing my invention I adjust to curbstone A, which rests between sidewalk B and paved street 0, curb-cap D, which is made of wroughtiron. One end of cap rests under flag of sidewalk, and bow of cap clasps curb stone, as shown by D in Fig. 2. On the portion of curb-cap which projects over side of curbstone in the direction of street are openings for screws for adjusting hangers E, said hangers projecting downward from four to six inches. Metal plates F are constructed of cast-iron and may be made ornamental, so as to include name of person on plate in front of residence, or name of street.

G represents wires placed on hangers E.

His position of wire as it enters dwelling.

In putting my invention into practical operation the wires may be insulated and placed on hangers or placed in a cable, and thus strung upon the hangers; or, where preferable,

any desired number of glass or porcelain insulators may be attached to hangers and the wires strung upon them. When a certain number of wires are placed into position, and it is desired to string additional wires, the plates covering wires, which are fastened with screws, can be readily removed and additional wires placed in position, or such as are not required may be removed, thus avoiding all danger of loss of life from defective arm or cross pieces attached to poles.

A striking advantage of my invention is that the wires are at all times accessible and occupy a position in the street that in no way obstructs the view, but renders the curbstone ornamental,and at the same time enables wires to be carried into a private dwelling without injuring the roofs of buildings, which is now such a source of annoyance, and avoids all unsightly obstructions, such as poles.

I am aware that it has been proposed to place wires in an underground conduit; but such a construction is not practicable on ac countof the expense, and at the same time the difficulty in securing a position underground in cities for a conduit for wires is great on account of the water, gas, and sewer pipes, and dampness preventing a. proper working of the wires, and the wires are not in an accessible position. The stringing ofwires upon towers through the streets is also impracticable on account of expense and risk at tending same.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, 1s-

The combination of the cap D, adapted to embrace the top of a street-curb and having an inwardly-directed flange to pass beneath a pavement, the hangers E, having their outer ends formed as shown, and the removable metallic plates F, adapted to be secured to the top of the hangers in advance of the curb and form a shield for wires or the like, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

MADISON DALLAS.
